Salt Lake City, Utah-based Infopia, a provider of e-commerce tools, said this morning that it has added support for eBay's new eBay Express website. eBay's new eBay Express website is a new feature of eBay that allows customers to find and buy items at a fixed price, rather than at its usual auction format. eBay Express also allows customers to purchase items from multiple sellers in a single shopping cart. Infopia said it will allow its users to make listings available through eBay's auctions also available through eBay Express. Infopia is backed by BC Select Fund, Hummer Winblad, Transpacific, and Trident Capital.
